Decodes YOUR signed EIP-3009 authorization and hands it back field by field — payer, value, recipient, validity window, nonce — so you can see exactly what the server received. Signing bugs are miserable to debug because the only feedback is usually "invalid"; this shows you which field is wrong. Free simulated failure cases live at https://soren.com/v1/conformance

Soren · Free Games

soren.com

Every PC game currently free to KEEP (claim once, own permanently) across Steam, Epic Games Store, GOG and itch.io. Each entry verified against that store's own API before publication. Per-store status distinguishes "verified: nothing is free" from "could not check", so a zero is a fact rather than an absence of data. Self-verifying: the version field is a SHA-256 of the payload's own content.

Soren · AI Judge

soren.com

A neutral, SIGNED verdict on whether a deliverable meets stated criteria, or which of two candidates is better. Neither party to an A2A transaction can referee it — this is a party with no stake, signing over the SHA-256 of the exact bytes judged. Identical inputs return the identical verdict for 30 days, so verdict-shopping is impossible. Fix criteria first with /v1/commit. Charged only if a verdict is produced.

Soren · Paid Ping

soren.com

A heartbeat that costs money, and therefore proves more than a health check: not merely that the server answers, but that x402 verification and settlement are working right now, end to end. Suitable for a monitor that needs to know the PAID path is alive.
